Cradle cap is a common, harmless skin condition in babies that causes greasy, yellow scales on the scalp. It isn’t contagious, doesn’t itch much, and usually clears on its own within weeks to months.
What it looks like
- Oily, yellow or white flakes on the scalp that can stick to hair.
- Mild redness under the scales.
- Sometimes also on eyebrows, behind ears, and in skin folds.
Why it happens
- Likely related to natural skin oils and a common skin yeast. It’s not due to poor hygiene or allergies.
Gentle home care
- Softening: Before bath, massage a small amount of baby oil, mineral oil, or petroleum jelly onto the scalp for 15–30 minutes to loosen scales.
- Washing: Use a gentle baby shampoo; during the bath, gently brush with a soft baby brush or a fine-tooth baby comb to lift flakes. Don’t scratch—be gentle.
- Frequency: 2–3 times a week is usually enough; daily if very scaly, then taper to maintenance.
If stubborn
- Anti-dandruff shampoos (ketoconazole 1%, selenium sulfide, or zinc pyrithione) can be used 2–3 times weekly short-term. Avoid eyes; rinse well. Ask your pediatrician first, especially for very young infants.
- For inflamed areas (red and irritated), your clinician may recommend a short course of a mild steroid lotion.
When to seek care
- Spreads widely, looks very red or weepy, or has a bad odor (possible infection).
- Your baby seems uncomfortable, has fever, or the rash involves the diaper area severely.
- If you’re unsure whether it’s cradle cap or eczema/other conditions.
What to expect
- Most cases improve with simple care. It can flare and fade; consistent gentle routine helps.
- Hair may shed with the scales—this will regrow.
